CBS 'asks Grammy stars to cover up'

Stars are being asked not to bare too much skin at the Grammy Awards on Sunday, according to reports.

America's CBS network is reportedly requesting that "buttocks and female breasts are adequately covered" for the televised award show, which will include performances from the likes of Rihanna, Alicia Keys and Taylor Swift.

The memo sent out on Wednesday also warned against "see-through clothing", exposure of "the genital region" and said that "thong type costumes are problematic".

Representatives for CBS and the Recording Academy declined to comment on Thursday. Deadline Hollywood first reported the memo.
